An investigation of trauma-associated appraisals and posttraumatic stress disorder in British and Asian trauma survivors: the development of the Public and Communal Self Appraisals Measure (PCSAM).

Two studies examined the role of culture on cognitive appraisals of trauma and associated implications for posttraumatic psychological adjustment. Study 2 also investigated the reliability and validity of a new measure assessing public and communal aspects of trauma-associated appraisals (Public and Communal Self Appraisals Measure; PCSAM). Study 1's non-clinical sample (N = 75) and Study 2's sample of British and Asian trauma survivors with and without PTSD (N = 95) provided an everyday and trauma memory, completed an Appraisal Inventory, the Posttraumatic Cognitions Inventory and measures of PTSD. Study 2 participants also completed the PCSAM. Conjoined, there were cultural differences in appraisals of everyday and trauma experiences. Nonetheless, there appeared to be cultural similarities in the dysfunctional appraisals of those with PTSD. The PSCAM had good internal consistency, test-retest reliability, convergent validity, and discriminative validity. Findings are discussed in terms of combining cultural models of self with current PTSD models.
